Since you listen to vinyl only, I assume you have an active phono stage. You may want to consider upgrading that instead. I say this because you know the value of a passive line stage. $1500 is a hard price point to work with, even for a used active preamp.
I'm not saying that you can't get anything good. Depending on what you like, it may be possible; just difficult. If it were me, I wouldn't get anything without trying it in my system first.
